Evidence boundaries
Organisation listings identify a reviewed canonical record. Model listings show an association in the source register; they do not by themselves establish model creation, current API availability, hosting location or infrastructure ownership.
Profile note
Recorded as a European LLMOps loss, not a live company. A UCL spin-off (2020) that became the leading prompt-management, LLM-evaluation and observability platform; in August 2025 Anthropic acqui-hired the co-founders and ~a dozen engineers and researchers into its Product & Engineering leadership, explicitly WITHOUT acquiring the assets or IP, and the platform wound down. A clean illustration of the European AI-tooling talent drain to US frontier labs.
